Congrats on these beautiful noodles! I'm also making the transition to working out of the house (I worked from home for the first few weeks so we could do alone training gradually). It's pretty stressful (for me) but Dino just whines a little after I leave and then goes back to torturing his squeaky toys, so I think it's going pretty well. Use of Kongs and leaving music on seem to help. It's good that they have each other. I've found that modeling calmness can be a great help with showing a dog there's nothing to be anxious about, so having another dog there to do that seems like a great bonus to having two!
